About this study

The purpose of this study is to determine the psychometric properties of the Knowledge, Attitudes, and Beliefs about Atrial Fibrillation Survey (KABAFS) and to generate critical, practical knowledge about the feasibility of conducting a randomized trial to test the effect of the Alert for Atrial Fibrillation program on treatment-seeking for symptoms of Atrial Fibrillation (AF).

Study phase:

During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

Colchicine will lower C-reactive protein (CRP) in chronic atrial fibrillation and reduce the rise in CRP which occurs following atrial fibrillation ablation.

About this study

The purpose of this study is to compare edoxaban (investigational drug) with warfarin and enoxaparin, to see if it is safe and effective in preventing stroke and other blood clot complications in subjects with atrial fibrillation whose doctors plan to treat them with an electrical cardioversion. It is expected that 284 sites will recruit 2200 subjects from North America, EU, Russia, Ukraine and Israel. Participants will be randomly allocated to receive either treatment with edoxaban, or treatment with warfarin, plus enoxaparin if required. Participants will have an equal chance of receiving either treatment. Participants will be in the study for a maximum of 82 days. Study procedures will include physical examinations, vital signs (pulse and sitting blood pressure), ECG (electrocardiogram), finger prick blood clotting tests, blood samples, urine samples and completion of Quality of Life questionnaires. The study is expected to show that edoxaban will provide comparable incidence rates for efficacy to warfarin plus enoxaparin, the current standard treatment, and will be at least as safe as warfarin for the incidence rate for bleeding

About this study

VICTORY AF is an IDE, prospective global, multi-center, single arm, controlled, unblinded, investigational clinical study. The purpose of this clinical study is to evaluate the risk of procedure and/or device related strokes in subjects with persistent or long-standing persistent atrial fibrillation (AF) undergoing ablation with the Phased RF System.

About this study

The (Catheter Ablation Versus Anti-arrhythmic Drug Therapy for Atrial Fibrillation Trial) CABANA Trial has the overall goal of establishing the appropriate roles for medical and ablative intervention for atrial fibrillation (AF). The CABANA Trial is designed to test the hypothesis that the treatment strategy of left atrial catheter ablation for the purpose of eliminating atrial fibrillation (AF) will be superior to current state-of-the-art therapy with either rate control or rhythm control drugs for decreasing the incidence of the composite endpoint of total mortality, disabling stroke, serious bleeding, or cardiac arrest in patients with untreated or incompletely treated AF.

About this study

The study will determine the benefit of Colchicine versus placebo for cardiac surgery patients on the post-operative development of atrial fibrillation and post-pericardiotomy syndrome.

Primary Objective. Colchicine will reduce the composite endpoint of incidence of post-operative atrial fibrillation and post-pericardiotomy syndrome at 3 months following cardiac surgery.

Secondary Objectives.

Colchicine will reduce the incidence of constrictive physiology on echocardiography at 3 months following cardiac surgery.

Reduction in the burden of symptomatic and asymptomatic atrial fibrillation in the 3 months following cardiac surgery with the use of colchicine.
